内容記述 | A magnesium (Mg) solid solution with a long periodic hexagonal structure was found in a Mg97Zn1Y2 (at.%) alloy in a bulk form prepared by warm extrusion of atomized powders at 573 K. The novel structure has an ABACAB-type six layered packing with lattice parameters of a = 0.322 nm and c = 3 ~ 0.521 nm. The Mg solid solution has fine grain sizes of 100 to 150 nm and contains 0.78 at.% Zn and 1.82 at.% Y. In addition, cubic Mg24Y5 particles with a size of about 7 nm are dispersed at small volume fractions of less than 10% in the Mg matrix. The specific density (ƒÏ) of the extruded bulk Mg-Zn-Y alloy was 1.84 Mg/m3. The tensile yield strength (ƒÐy) and elongation (ƒÂ) are 610 MPa and 5%, respectively, at room temperature, and the specific yield strength defined by the ratio of ƒÐy to ƒÏ is as high as 3.3 ~ 105 Nm/kg.
